Bug report
Following the accepted answer here, I'm unable to load the pickled plot.
I am doing this inside an ipython shell.
Actual outcome
# creating the file (session 1)
import matplotlib.pyplot as plt
import numpy as np
import pickle
ax = plt.subplot(111)
x = np.linspace(0, 10)
y = np.exp(x)
plt.plot(x, y)
pickle.dump(ax, file('myplot.pickle', 'w'))Followed by
# attempting to load the file (session 2)
import matplotlib.pyplot as plt
import pickle
ax = pickle.load(file('myplot.pickle'))
plt.show()Results in:

- How did you install Matplotlib and Python (pip, anaconda, from source ...)
I didn't install it, myself, it's the lab stack. It looks like anaconda.
